International audience. Abstract Background and purpose Patients with acute ischaemic stroke and a large vessel occlusion who present to a non‐endovascular‐capable centre often require inter‐hospital transfer for thrombectomy. Whether the inter‐hospital transfer time is associated with 3‐month functional outcome is poorly known. Methods Acute stroke patients enrolled between January 2015 and December 2022 in the prospective French multicentre Endovascular Treatment of Ischaemic Stroke registry were retrospectively analysed. Patients with an anterior circulation large vessel occlusion transferred from a non‐endovascular to a comprehensive stroke centre for thrombectomy were eligible. Inter‐hospital transfer time was defined as the time between imaging in the referring hospital and groin puncture for thrombectomy. The relationship between transfer time and favourable 3‐month functional outcome (modified Rankin Scale 0–2) was assessed through a mixed logistic regression model adjusting for centre and symptom‐onset‐to‐referring‐hospital imaging time, age, sex, diabetes, referring hospital National Institutes of Health Stroke Scale score, Alberta Stroke Programme Early Computed Tomography Score, occlusion site and intravenous thrombolysis use. Results Overall, 3769 patients were included (median inter‐hospital transfer time 161 min, interquartile range 128–195; 46% with favourable outcome). A longer transfer time was independently associated with lower rates of favourable outcome ( p < 0.001). Compared to patients with transfer time below 120 min, there was a 15% reduction in the odds of achieving favourable outcome for transfer times between 120 and 180 min (adjusted odds ratio 0.85; 95% confidence interval 0.67–1.07), and a 36% reduction for transfer times beyond 180 min (adjusted odds ratio 0.64; 95% confidence interval 0.50–0.81). Conclusions A shorter inter‐hospital transfer time is strongly associated with favourable 3‐month functional outcome. A speedier inter‐hospital transfer is of critical importance to improve outcome.
